Vortices and the SU(3) string tension
We present simulation results comparing the SU(3) heavy quark potential extracted from the full Wilson loop expectation to that extracted from the expectation of the Wilson loop fluctuation solely by elements of Z(3). The two potentials are found to coincide. This agreement is stable under multiple smoothings of the configurations which remove short distance fluctuations, and thus reflects long...
متن کاملSU(3) string tension and the presence of vortices
Lattice simulations are presented showing the expectation of the fluctuation of the Wilson loop solely by elements of the center to fully reproduce the SU(3) heavy quark potential. The results are stable under smoothing, and point to thick vortices as being responsible for the full SU(3) tension. An analytic result on the necessary presence of thick vortices for confinement at weak coupling is ...
متن کاملThe Holomorphic Tension of Vortices
We study the tension of vortices in N = 2 SQCD broken to N = 1 by a superpotential W (Φ), in color-flavor locked vacua. The tension can be written as T = TBPS + TnonBPS. The BPS tension is equal to 4π|T | where we call T the holomorphic tension. This is directly related to the central charge of the supersymmetry algebra. Using the tools of the Cachazo-Douglas-Seiberg-Witten solution we compute ...
متن کاملZ ( 2 ) vortices and the string tension in SU ( 2 ) gauge theory ∗
We report on recent work on the crucial role of vortices characterized by Z(N) flux for maintaining confinement at weak coupling in SU(N) gauge theory. The present work is a continuation of our on-going project over the last several years [1]. We begin by distinguishing between various types of vortices. Recall that in the continuum formulation there is no local distinction between pure SU(N) a...
متن کاملCenter Vortices
We review recent progress in understanding the center-vortex picture of con nement for SU(N). A notable development is the spectacular con rmation on the lattice of center-vortex predictions for topological con nement and the area law in the fundamental-representation Wilson loop. Recent theoretical progress includes: large-N scaling, the heavy-quark potential for SU(3) baryons, the breakable \...
